Mamba Switches pay tribute to a legend. They're constructed with the extremely smooth molds the community is familiar with from JWK. They feature an extended long pole stem made of LY for exceptionally satisfying bottom-out feel and acoustics. This is coupled with an improved factory lubing technique, making them arguably great without modding. 

What is LY?

LY is an UHMWPE blend made by JWK aimed to combine UHMWPE's natural lower coefficient of friction, self-lubricating properties, and resistance to abrasion with enhanced structural integrity. UHMWPE on its own is an extremely soft material prone to deforming in instances of high stress such as when stems are friction fitted into keycaps. This can result in wobble, or in extreme cases keycaps simply falling off. This blend ensures those issues do not occur. Additionally, the increased rigidity will produce a louder, fuller sound on bottom-out than a comparable pure UHMWPE stem.


Switches are sold in packs of 10.
